2006 DODGE DURANGO coolant temperature

WARNING!
The warning words “DO NOT OPEN HOT” on the
coolant pressure cap are a safety precaution. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap when the system is hot or under pressure.
Coolant Level
The coolant bottle system provides a quick visual method
for determining that the coolant level is adequate. With
the engine idling, and warmed to normal operating
temperature, remove the cap from the bottle, remove the
dipstick and wipe the excess coolant from it. Reinsert the
dipstick and remove. Observe the dipstick checking the
holes along the stem for coolant. Check the coolant level
whenever the hood is raised.The radiator normally remains completely full, so there is
no need to remove the pressure cap except checking
coolant freeze point or replacement with new antifreeze
coolant. Your service attendant should be advised of this.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
A. Do not overfill the coolant bottle.
B. Check coolant freeze point in the radiator and in the
coolant bottle. If antifreeze needs to be added, contents of
coolant bottle also must be protected against freezing.
C. If frequent coolant additions are required, or if the
level in the coolant bottle does not drop when the engine
cools, the cooling system should be pressure tested for
leaks.
